net: ravb: Set config mode in ndo_open and reset mode in ndo_close

Browse source

As some IP variants switch to reset mode (and thus the register contents is
lost) when setting clocks (due to module standby functionality) to be able
to implement runtime PM and save more power, set the IP's operating mode to
reset at the end of the probe. Along with it, in the ndo_open API the IP
will be switched to configuration, then operation mode. In the ndo_close
API, the IP will be switched back to reset mode. This allows implementing
runtime PM and, along with it, save more power when the IP is not used.
